First you need to graph the coordinate points to see the triangle.
Then you need to drop lines down on the graph to form right triangles and use Pythagorean Theorem.
The line of points -5,-1 and -2,3 measures 5 using Pythagorean theorem.
The line of points 6,-3 and -5,1 measures √125
The line of points 6,-3 and -2,3 measures 10 using Pythagorean theorem.
So...
5 + 10 = 15
15 + √125

Answer: 8 batches
Step-by-step explanation:
To get the number of batches she made, we can just use proportion to solve it. But first, we need to convert 5 1/3 to improper fraction
5 1/3 = 16/3
Then we can now use the proportion to solve
2/3 cups = 1 batch
16/3 cups = x (note:5 1/3=16/3)
cross multiply
2/3 × x = 16 /3
2x/ 3 = 16/3
we need to make x the subject of the formula, to do that we will multiply each side of the equation by 3/2
2/3 × 3/2 x = 16/3 × 3/2
6x /6 = 48 / 6
x = 8
Therefore she made 8 batches of cookies.
I believe your answer is D. y = x/9.
